CHARACTERIZATION & SIMULATION Energy storage system with high durability and power density
As 14 % of the world’s 2010 greenhouse gas emissions came from cars, trucks and other vehicles, plans exist to reach 125 m electric vehicles by 2030. However, by 2018, the total was only 5.1 m. Accordingly, developing an economically-viable fast-charging infrastructure has become of interest, to accelerate the changeover to EVs.
However, 33 % of 2018 US CO2 emissions were related to energy production, mainly from coal-fired power stations. To overcome this, massive deployment of renewable energy sources such as solar panels and wind turbines has become mandatory – but this requires a grid-tied energy storage system to balance energy production and consumption demands and to help grid stabilization.
Past energy storage systems composed of supercapacitors were not competitive with lithium ion batteries for energy and power density, making such systems economically unviable. Accordingly, current research efforts are looking at new types of carbon based supercapacitors to increase the performance metrics while simultaneously decreasing production costs.
